Sharepoint 2013 online: Retrieve email address of an active directory user via JavaScript Object model

Question

I have set up a working connection between my sharepoint 2013 online and my Active directory, what I'm trying to achieve is to retrieve a specific field (in this particular case an email address field) of an user in Active Directory, does anyone knows if there is a way to do that only via client side script (JavaScript)? If so, can anyone provide me some readings or some code? Thanks very much.

IMPORTANT: I don't need/want to import them in a list, I just need to read them directly from AD.

Considering that you have run a AD synchronization with your UPSA and that your AD connection rules include the OU of the user you are querying for, you should be able to retrieve the specific AD fields (in this case email) using JSOM. Check SP.Userprofiles (https://msdn.microsoft.com/en-us/library/office/jj920104.aspx)

var userProfileProperties;

// Ensure that the SP.UserProfiles.js file is loaded before the custom  code runs.
SP.SOD.executeOrDelayUntilScriptLoaded(getUserProperties, 'SP.UserProfiles.js');

function getUserProperties() {

// Replace the placeholder value with the target user's credentials.
var targetUser = "domainName\\userName";

// Get the current client context and PeopleManager instance.
var clientContext = new SP.ClientContext.get_current();
var peopleManager = new SP.UserProfiles.PeopleManager(clientContext);

// Specify the properties to retrieve and target user for the 
// UserProfilePropertiesForUser object.
var profilePropertyNames = ["Email"];
var userProfilePropertiesForUser = 
    new SP.UserProfiles.UserProfilePropertiesForUser(
        clientContext,
        targetUser,
        profilePropertyNames);

// Get user profile properties for the target user.
// To get the value for only one user profile property, use the
// getUserProfilePropertyFor method.
userProfileProperties = peopleManager.getUserProfilePropertiesFor(
    userProfilePropertiesForUser);

// Load the UserProfilePropertiesForUser object and send the request.
clientContext.load(userProfilePropertiesForUser);
clientContext.executeQueryAsync(onRequestSuccess, onRequestFail);
}

// This function runs if the executeQueryAsync call succeeds.
function onRequestSuccess() {
var messageText = "\"Email\" property is " 
    + userProfileProperties[0];
$get("results").innerHTML = messageText;
 }

     // This function runs if the executeQueryAsync call fails.
function onRequestFail(sender, args) {
    $get("results").innerHTML = "Error: " + args.get_message();
}
